Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I installed a new F14 system on my Acer Aspire One, but here's the problem: The installer asked for a root password on installation, right? Well, typing that in when I rebooted (and after it reportedly installed correctly) returned an "Authentication Failure" error -- the exact same password, I even typed it in twice to make sure!

After doing all this while booting from the Live CD and mounting the root drive:

1. fromm the GRUB menu hit e for edit
2. select the kernel line and hit e again for edit
3. append 'single' to the line and hit enter
4. hit b for boot and hopefully it drops you at a root prompt
5. remount / read/write (`mount -o remount,rw /`)
6. type passwd and reset the root passwd

I tried that too, but whenever I do that I get something along the lines of a "Permission Denied" error (with lengthy Python expressions, of course) and a slap in the face. I now have a chroot set up in which I am able to type commands on the SSD through the Live CD with root privileges. I now am upgrading my packages (after installing the "fedora-release-rawhide" package) and will then use passwd and see what it does.

It seems as though I got several warnings that SELinux prevented the invocation of passwd -- even as root -- on the live CD! How do I correct this? Where is SELinux Admin in F14 and how do I execute it? Trying to install GUI frontends for SELinux causes the PackageKit, as it is running, to get to "Resolving Dependencies" and then crash.

Have you tried putting selinux into non-enforcing mode? /etc/selinux/ is the path to the configuration file. Good luck.

This is what ultimately allowed me to log in to my upgraded FC13->FC14 system. I suspected bad labels, but a 'restorecon -RFv /' didn't help. Neither did relabeling on boot. There's something wrong with the SELinux policy but I'm not enough of a guru there to diagnose it.
